Ammunition for Tanks 120 mm DM 63 KE Cartridge

Product Description

The DM63 cartridge is based on the already fielded DM53. The essential difference between the two cartridges lies in the propulsion unit. Instead of a conventional propulsion unit, the DM63 is the first 120mm high-performance KE round to be equipped with a temperature-independent propulsion system (TIPS®), based on SCDB® technology.

Apart from temperature-independent performance data,the design of the propulsion unit of the DM63 was aimed not so much at achieving an improvement in performance but instead at attaining a distinct reduction in erosion while maintaining the same level of performance (+15°C same vo as DM53). To achieve this objective in optimum fashion, the one-piece combustible case was modified with respect to the erosionreducing characteristics of its combustion gases.

The intended vo of 1,650 m/s (L44) is attained with a pure bulk powder charge featuring a mass of approx. 8.45 kg and a maximum gas pressure of approx. 545 MPa. Taking into account the cartridge conditions arising under typical operational circumstances in climate zone A3, the temperature performance in the L44 develops as follows: The span of vo and pressure throughout the entire temperature range is less than 60 m/s and 60 MPa. At low temperatures, the gain in performance is particularly noticeable, as is the avoidance of unnecessarily high pressure and performance levels at high temperatures with respect to terminal ballistics.Main features
